Answer:

b)

Step-by-step explanation:

The line with positive slope is 3x-5y≥15 and the line with negative slope is 2x+3y≤12.

This is because such inequalities represent half planes which are divided by the corresponding lines.

Put (0,0) in both lines to check if the origin lies in the shaded half plane or not.

Use the calculator to graph the function y = 2x2 25x + 3. What are the coordinates of the turning point of the graph to the near
olga2289 [7]

Use the calculator to graph the function y = 2x^2+ 25x + 3

In the graph , the coordinates of the vertex is the turning point of the graph.

Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.

There will be only one turning point for parabola

Turning point is the vertex

To find vertex we use formula x= \frac{-b}{2a}

y = 2x^2+ 25x + 3

a=2, b= 35

x =\frac{-25}{2*2}  =\frac{-25}{4} = -6.25

Now plug in \frac{-25}{4} in f(x)

y= 2(\frac{-25}{4})^2+ 25(\frac{-25}{4})  + 3

Take common denominator

y= \frac{625}{8}+ (\frac{-625}{4})  + 3 =\frac{625-1250+24}{8} =-\frac{601}{8} = -75.125

So coordinates of turning point is (-6.25, -75.13)

The graph is attached below.

If 30g of sugar is needed to make 4 cakes how much grams of sugar is needed to make 7 cakes
arsen [322]
There's two ways to do this.

The first way:
Work out the amount of sugar needed to make one cake, and then multiply that by 7.

30 grams ÷ 4 cakes = 7.5 grams for 1 cake.
7.5 grams × 7 cakes = 52.5 grams for 7 cakes.

The second way:
Work out the ratio of sugar:cake by doing 7 ÷ 4, and then multiplying that value by 30.

7 cakes ÷ 4 cakes = 1.75
1.75 × 30 grams = 52.5 grams for 7 cakes. 

Either way, the answer is 52.5 grams.

Use the graph to write the factorization of x^2+2x-8
kozerog [31]

Answer:

(x-2)(x+4)

Step-by-step explanation:

So it would be A.

Explanation: The middle number is 2 and the last number is -8.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 2

Multiply together to get -8

Can you think of the two numbers?

Try -2 and 4:

-2+4 = 2

-2*4 = -8

Fill in the blanks in

(x+_)(x+_)

with -2 and 4 to get...

(x-2)(x+4)

Answer:

(x−2)(x+4)
